COMBINED STEAM AND HOT-WATER HEATER.

SPECIFICATION forming part Of Letters Patent No. 343,431, dated June 8, 1886.

3 Application filed April 29, 1885. Serial No. 163,815. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM J. BOWER- I MAN, of Detroit, in the county of Wayne and State of Michigan, have invented new and useful Improvements in Combined Steam and Hot-Water Heaters; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to a new and useful improvement in steam-heaters; and the invention consists in the peculiar arrangement and construction of an attachment to said heaters, by means of which an independent system of heating by hot-water may be combined with the steam-heating system.

It is the object of my invention, in providing the steam-heaters used for heating dwellings with a hot-water circulation, to furnish either additional heating facilities for heating conservatories by hot water, or to furnish hot water for use in bath-rooms, 850. .All these objects I intend to accomplish by providing the steam-heater with an attachment which is independent from the steam-heater, but which is so combined with it that it may utilize a large part of the waste heat Without interfering with the efficiency of the steamheater, and its construction will adapt it to be used in connection with most or all of the different styles of upright boilers generally used for steam-heating purposes in dwellinghouses, and it may be connected, disconnected, or removed from a steam-heater without materially disturbing the same.

In the drawings which accompany this speoi fication, Figure l is a vertical central section showing my hot-water-circulating attachment applied to a steam-heater of the usual vertical type of steam-boiler. Fig. 2 is a horizontal section on line 00 a: in Fig. 1. Fig. 3 is a detached perspective View of the hot-water attachment. Fig. 4 is a central vertical section of a hot-water boiler corrugated upon the inside for its entire length.

A is a steam-heater of the general type in use for heating residences and other private dwellings, and wherein the boiler is a socalled upright one. The heater shown in the drawings consists of two sections connect ed by a series of vertical pipes, B, circularly arranged around the combustion-chamber G, and provided with open spaces between the pipes through which the gases of combustion escape to the outside. This kind of boiler I consider especially adapted for use in connection with my attachment, as it renders the latter especially efiicient.

D is aring-shaped hot-water boiler of a diameter a little larger than the diameter of the steam-heater, so that it may be readily slipped on or off the same. This hot-water heater I place around the lower section of the steam-heater, where it will get the most heat from proximity to the combustion-chamber, supporting it in any suitable way as the circumstances permit. To provide for the exit of smoke I either makethis boiler short enough to allow the smoke to pass over the top, or I make it corrugated upon the inside either the whole height, as shown atK in Fig. 4, or only near the top, as shown in Fig. 3. To this hotwater boiler I connect in the usual manner a system of hot-water-circulating pipes, E, provided with safety-valve and fill-opening, and when used for furnishing hot water to bathrooms, 850., I connect it also with the servicepipe.

I am aware of the Patents Nos. 308,855, 311,02I,and 311,533, and make no claim to the constructions shown therein as forming part of my invention.

I deem it important that the hot-water boiler D be arranged. entirely independent of the steam-heater, and that the pipeconnections with said boilerbe outside of and independent of the heater, for by this arrangement the boiler may be connected, disconnected, or removed without materially disturbing the heaters.

What I claim as my invention is 1. In a device for the purposes described, an upright cylindrical steamheater, combined with an annular hot-water boiler surrounding said heater, in proximity to the coinbustion-chamber, but entirely independent of said heater, and provided with a series of hot water-circulating pipes arranged outside of and independent of the steam-heater, whereby the said hot -water boiler may be removed without disturbing the steam -heater, as set forth.
